## Questions & Answers

**Q: With on of these fitted to a 3s 18650 battery , can i use a 12v charger designed for SLS battery will the board cut the charging off when its reached**
A: I don't believe you can. My board is used to charge a 12.6V 18650 battery pack with a similar output battery charger

**Q: Can the input be a 12 volt solar panel?**
A: No you need a proper BMS controller for solar panels.

**Q: Could anyone tell me the low voltage cutoff point?**
A: It’s approximately 3.4V lower and 4.2v for the high point per cell. So x that by 3 to get the value. 10.4 & 12.6v for a 3S charger.

**Q: What is the input voltage? can you use usb charger to recharge the batteries?**
A: Hello, this can not be charged, the input voltage is DC 12.6-13V
